Background

The application of stamping in the field of machine manufacturing is quite extensive, and most metal plates are formed by stamping. The production mode of multi-variety and small-batch production needs to increase the die change times of the stamping die and reduce the single production quantity for the sheet metal enterprises. The increase of the times of die change shortens the effective production time and reduces the production efficiency. The rapid die change is the premise of realizing balanced production of various small-batch production enterprises. After the production of a product is finished, operations such as tool replacement, raw materials, molds and the like of a production line need to be suspended, and the rapid mold replacement technology achieves the purposes of effectively shortening the product switching time and improving the equipment utilization rate and the personnel operation efficiency by shortening the product mold replacement time and the equipment starting and adjusting time, and has important significance on production competitiveness.

For a small punch, when a die is replaced, a male die and a female die body need to be replaced manually, the male die needs to be customized, machined and installed at the punch of the punch, the female die body needs auxiliary devices such as a base plate and the like to be fixed on the punch through bolts, then the die closing height and the hole aligning of a new die need to be measured, the die closing accuracy needs to be guaranteed, and the mode is very complicated and inaccurate. In the current market, the types of stamping die change equipment can be divided into two types, one type is a stamping die change for processing micropores by a high-end precision instrument, the other type is a punching die change for building plates and structural plates, corresponding large die change equipment is already available in the high-end precision market, and in the aspect of punching structural plates or angle steel punching, a process for punching by using a small punch press is a manual die change which is used, the reason is that the die change operation is complex and the precision requirement is high, manual operation also needs to be stopped, and the continuous operability of the equipment is influenced. In a word, when the product type is converted, the operation continuity is difficult to realize, the die is replaced after the operation of the equipment is stopped, the complex degree of die changing operation is high, and the manual shutdown and replacement are needed.
